As I'm still working on my Ph.D. dealing with videogame perception in Germany and Australia my blogroll naturally differs from Parker's: It's pretty game heavy probably not as surprising or original. Anyway, here're some of my regularly frequented blogs:
Gamepolitics: "Where politics and video games collide". The essential source for legal matters, censorship debates, game legislation issues, politicians' stand on digital games, all things Jack Thomspon and games trying to bring across a message. Well written and easily accessible despite the sometimes demanding subject matter.

Destructoid: Founded by hardcore gaming fans for hardcore gaming fans. Taking itself and the industry not too seriously yet surprisingly insightful, they are not afraid to advance unpopular opinions – out of conviction and not for the attention. Also features a community that is actually able to exchange interesting thoughts without adding too many insults. (One of the few sites whose users didn't threaten to kill my old lecturer and friend Jason Nelson after his project "Game, game, game and again game" got covered)

Screenplay: The Australian authority on digital games and my main resource for Australia related gaming news. Offers good interviews with those involved in the (Australian) industry and keeps a close eye on policy developments. Best enjoyed in combination with Tsumea, one of the main resources for Australian and New Zealand game developers.

Popurls: Technically not a blog but a feed aggregator collecting the latest stories from digg, delicious, reddit, metafiler, stumbleupon, slashdot, wired… Incredibly addictive yet also a great social graph of the web.

Twitter: a whole bunch of microblogs by a whole bunch of smart people.

Since I spend the longest part of my day either reading or writing I try and relate some of the stuff I come across in old-fashioned books to issues that are relevant to blogcampaigning, especially since whatever occurs in the tech/PR/game world are not isolated incidents but imbedded into a social frame, e.g. a post I still would like to work on is how social shopping is an expression of the aesthetization of everyday life caused by a shift of the fundamental semantic of society away from an economic paradigm towards a psycho-physical one… (Parker's note: I'm only letting you write that post if you use regular words)

We write about advertising, technology, public relations, social media, video games, marketing and pretty much whatever we feel is important. We've been around since August, 2006. Right now, It's mostly written by Parker Mason.
